入选标准

  • 1. Women aged >18years.
  • 2. Histologically proven DCIS of the breast without an invasive component.
  • 3. Bilateral mammograms performed within 6 months prior to randomisation.
  • 3. Clinically node-negative.
  • 4. Treated by breast conserving surgery (primary excision or re-excision) with complete microscopic excision and clear radial margins of greater than or equal to 1mm (Patients with superficial or deep resection margin of <1 mm are eligible if surgery has removed all of the intervening breast tissue from the subcutaneous tissue to the pectoralis fascia)
  • 5. Women who are at high risk of local recurrence due to: Age < 50 years; OR Age = 50 years plus at least one of the following: a) Symptomatic presentation
  • b) Palpable tumour c) Multifocal disease
  • d) Microscopic tumour size = 1.5 cm in maximum dimension e) Intermediate or high nuclear grade f) Central necrosis
  • g) Comedo histology h) Radial* surgical resection margin < 10 mm*Patients with superficial or deep resection margin of < 10 mm are eligible if surgery has not removed all of the intervening breast tissue from the subcutaneous tissue to the pectoralis fascia.
  • 6. Assessed by surgeon and radiation oncologist to be suitable for breast conserving therapy including whole breast RT.
  • 7. Ability to tolerate protocol treatment.
  • 8. Protocol RT should preferably commence within 8 weeks but must commence no later than 12 weeks from the last surgical procedure
  • 9. ECOG performance status 0, 1 or 2.
  • 10. Patient’s life expectancy > 5 years
  • 11. Availability for long-term follow-up.
  • 12. Written informed consent.

排除标准

  • Patients who fulfil any of the following criteria are not eligible for admission to study:-
  • 1. Multicentric disease or extensive microcalcifications that could not be completely excised by breast conserving surgery with radial margins of greater than or equal to 1mm (Patients with superficial and/or deep margin of < 1mm are eligible if surgery has removed all of the intervening breast tissue from the subcutaneous tissue to the pectoralis fascia)
  • 2. Presence of tumour cells in lymph nodes detected using H&E or immunohistochemical examination (if lymph node biopsy or dissection has been performed).
  • 3. Locally recurrent breast cancer.
  • 4. Previous DCIS or invasive cancer of the contralateral breast.
  • 5. Other concurrent or previous malignancies except: a) Non-melanomatous skin cancer; b) Carcinoma in situ of the cervix or endometrium; and
  • c) Invasive carcinoma of the cervix, endometrium, colon, thyroid and melanoma treated at least five years prior to study admission without disease recurrence.
  • 6. Serious non-malignant disease that precludes definitive surgical or radiation treatment (e.g. scleroderma, systemic lupus erythematosus, cardiovascular/pulmonary/renal disease).- 7. ECOG performance status = 3.
  • 8. Women who are pregnant or lactating.
